Abstract

Additives and methods for reducing or eliminating odor in oil based media. The additives comprise an essential oil, an essential oil component, or mixtures thereof.

1. A method for reducing odor in oil based media, said method comprising mixing an odor reducing amount of an odor reducing additive with an oil based medium, wherein the odor reducing additive is a mixture of essential oils, a mixture of essential oil components, or mixtures thereof, wherein the odor reducing additive is diluted with a carrier oil, which is comprised of methyl esters of canola oil, ethyl esters of canola oil, the methyl ester of soybean oil, or a mixture thereof; and wherein the oil based medium is fuel oil, waste oil fuel oil, oil based synthetic lubricants, liquid asphalt cement, or hot mix asphalt. 
     
     
       2. The method of  claim 1  wherein the odor reducing additive comprises one or more essential oils selected from the group consisting of Rosemary oil, Cedarwood oil, Pine Needle oil, Eucalyptus oil, Clove oil, Thyme oil, Vetiver oil, Vanilla oleo resin, Lavender oil, and Tea Tree oil. 
     
     
       3. The method of  claim 1  wherein the odor reducing additive comprises one or more terpenes selected from the group consisting of α-pinene, .β-pinene, d 3 carene, dipentene, p-cymene, cineole, camphor, terpineol, bomyl acetate, cedrene, cedrol, and thymol. 
     
     
       4. The method of  claim 1  wherein the odor reducing additive comprises (+) limonene, pine extract and pine white oil, pinus sylvestris oil, anise seed oil, and clove bud oil. 
     
     
       5. The method of  claim 4  wherein the odor reducing additive further comprises aniseed oil, camphor white oil, cedarwood atlas oil, cedarwood texas oil, cedarwood virginia oil, lavandin absolute, lime distilled oil, olibanum extract, rosemary oil, sandlewood west indian oil, tocopherol alpha, and vanilla. 
     
     
       6. A method according to  claim 1 , wherein the odor reducing additive contains limonene. 
     
     
       7. A mixture having reduced odor comprising: an oil based medium; and an odor reducing additive, wherein the odor reducing additive is a mixture of essential oils, a mixture of essential oil components, or mixtures thereof, wherein the odor reducing additive is diluted with a carrier oil, which is comprised of methyl esters of canola oil, ethyl esters of canola oil, the methyl ester of soybean oil, or a mixture thereof; and wherein the oil based medium is fuel oil, waste oil fuel oil, oil based synthetic lubricants, liquid asphalt cement, or hot mix asphalt. 
     
     
       8. The mixture of  claim 7  wherein the odor reducing additive comprises one or more essential oils selected from the group consisting of Rosemary oil, Cedarwood oil, Pine Needle oil, Eucalyptus oil, Clove oil, Thyme oil, Vetiver oil, Vanilla oleo resin, Lavender oil, and Tea Tree oil. 
     
     
       9. The mixture of  claim 7  wherein the odor reducing additive comprises one or more terpenes selected from the group consisting of .alpha.-pinene, .beta.-pinene, d 3 carene, dipentene, p-cymene, cineole, camphor, terpineol, bomyl acetate, cedrene, cedrol, and thymol. 
     
     
       10. The mixture of  claim 7  wherein the odor reducing additive comprises (+) limonene, pine extract and pine white oil, pinus sylvestris oil, anise seed oil, and clove bud oil. 
     
     
       11. The mixture of  claim 10  wherein the odor reducing additive further comprises aniseed oil, camphor white oil, cedarwood atlas oil, cedarwood texas oil, cedarwood virginia oil, lavandin absolute, lime distilled oil, olibanum extract, rosemary oil, sandlewood west indian oil, tocopherol alpha, and vanilla. 
     
     
       12. The mixture of  claim 7  wherein the carrier oil is methyl esters of canola oil, the methyl ester of soybean oil, or a mixture thereof. 
     
     
       13. The mixture of  claim 7  wherein the oil based medium is waste oil fuel oil. 
     
     
       14. The mixture of  claim 13 , wherein the odor reducing additive contains limonene. 
     
     
       15. The mixture of  claim 7  wherein the oil based medium is liquid asphalt cement. 
     
     
       16. The mixture of  claim 15  further comprising an aggregate. 
     
     
       17. The mixture of  claim 16  wherein the aggregate is selected from the group consisting of crushed rock, fillers, gravel, stone, quarry gravel and recycled paving material. 
     
     
       18. The mixture of  claim 7 , wherein the odor reducing additive contains limonene.
